My friend's screen broke, and he has an old 3G ipod. We decided to take both of them apart and exchange the 3G screen which works, with the 4G one, that doesn't. We are still in the process of finding some hex drivers to take the board apart, and right now I am wondering if all our effects will seize to have a point, and it won't work. I also need to know how to properly take the screen off, because although i think it'll be easy, i still don't want to screw up the ipod.
